To change your wiki to have a more appealing look, follow the instructions below.

1. Click on MANAGE WIKI.
2. In the SETTING category, click LOOK AND FEEL.
3. Under this category, you can change the THEMES AND COLORS. (The theme for this wiki is Flexfluid and the color scheme is blue.) You should pay attention to the details of the different themes. If you like all your access to be at the top of the page, choose a theme in which you can easily view the wiki actions and your navigation bar. You can also customize the colors by selecting the Preview and customize button.
4. To return to the LOOK AND FEEL page, click the link in the upper right hand corner of your screen.
5. You can also change the look of your icon in the top portion of your wiki. Click LOGO.
6. On the LOGO page, you can browse for an image of your choosing. You must have a thumbnail picture of your image. If you wish to display the wiki name you need to type the wiki name with the picture. You can do this type of editing in Power point. When you are finished editing the photo and inserting a text box for a title, you group the picture as one. Save the picture and open it in the LOGO browser.

Here is a video with more information on how to edit the look & feel of your site:

Choose a theme for your site
Wikispaces offers a variety of pre-made themes to choose from. You can choose between placing the navigation bar on the right or left, having a banner at the top of your page, or even choosing a spiral notebook look for your wiki. Or you can fully customize your theme by editing your HTML and CSS. We encourage you to check out our different themes and find one that is right for you. To choose a theme:

1. Go to your wiki and then to “Manage Wiki.”
2. Click on “Look and Feel.”
3. Under “Theme,” click on the link “Change or make a new theme.”
4. On that next page, you can choose from one of our pre-made themes or, using HTML and CSS, fully customize and brand your wiki. Click “Apply” to set the theme you’d like for your wiki.

Set the colors for your theme
Once you have chosen the theme for your wiki, you can take a moment and personalize it by setting the colors of your wiki.

1. Go to “Manage Wiki” and then “Look and Feel.”
2. Under the “Colors” section of this page, you can set the colors for your text and different sections of the page.
3. Save your color selections.

Change the name of your wiki
By default, the name at the top of your wiki is the same as your wiki’s web address. If you would like to change the name at the top of your page:

1. Go to “Manage Wiki.”
2. Click on “Wiki Info.”
3. When you change the wiki name, this will not change the web address of your wiki. You can do this by changing the domain name on this page.

Change the logo for your wiki
Changing the logo on your wiki is a simple way to brand your wiki and give it a personal touch. To add your logo to the wiki:

1. Click “Manage Wiki” and go to “Look and Feel.”
2. In the “Logo” section in the page, click the “Browse” button.
3. Browse your hard drive for the image you want to use. The image you upload will appear at its actual size. If you’d like to change the size of your logo, use an image editor on your computer prior to uploading the logo to your wiki.
4. Click “Save” and your logo will appear at the top of your page.

Customize the navigation of your wiki
By editing the navigation bar on your wiki, you can set the structure of your wiki. This will help people navigate around your wiki and visit the pages you want them to access. By default, all new pages on your wiki are placed in your navigation bar. If you would like to customize which links appear there:

1. Click on the “edit navigation” link on the side of your page.
2. You will be editing your “space.menu” page, the page which contains all the content of the navigation bar.
3. You’ll see an “Include Page List” widget on that page. This is what automatically lists new wiki pages in alphabetical order in the navigation bar. Delete this widget.
4. List the page names or other text you would like in your sidebar.
5. Highlight each page name and link it to its appropriate page by clicking on the “Insert Link” tool in the toolbar.
6. Save the page.

Now change the logo on your project wiki to reflect the topic of your wiki.
